What is the spark plug gap for a 2009 Chevy Impala?
The recommended spark plug gap for a 2009 Chevy Impala is 0.044 inches (1.12 millimeters). This gap setting is crucial for the proper functioning of the vehicle's ignition system and engine performance.
Understanding Spark Plug Gaps
The spark plug gap refers to the distance between the center electrode and the ground electrode of a spark plug. This gap allows the spark to jump across and ignite the air-fuel mixture in the engine cylinder. The optimal gap size is specified by the vehicle manufacturer to ensure efficient combustion and prevent misfiring or other ignition-related issues.
Importance of Proper Spark Plug Gap
Maintaining the correct spark plug gap is essential for the 2009 Chevy Impala for several reasons:
- Improved Fuel Efficiency: A properly gapped spark plug can help the engine burn fuel more efficiently, leading to better fuel economy.
- Enhanced Engine Performance: The correct gap allows the spark to ignite the air-fuel mixture at the optimal time, resulting in improved engine power and responsiveness.
- Reduced Emissions: A properly gapped spark plug can help reduce harmful emissions by ensuring complete combustion of the fuel.
- Longer Spark Plug Life: Maintaining the recommended gap can extend the lifespan of the spark plugs, reducing the frequency of replacement.
It's important to note that the spark plug gap for the 2009 Chevy Impala may vary depending on the specific engine configuration and other factors. Always refer to the vehicle's owner's manual or consult a professional mechanic for the most accurate and up-to-date information.

What happens if spark plugs are not gapped correctly?
The incorrect plug gap for your engine can contribute to a high rate of misfires, loss of power, plug fouling, poor fuel economy and accelerated plug wear. It is always best to check the gap against the manufacturer's specifications.
What is the gap on a factory spark plug?
The gap setting is different for each vehicle but most are somewhere between 0.028" and . 060".
What is the spark plug gap on a 3.5 L V6?
Engine Specifications
| Engine | 2.7L EcoBoost | 3.5L V6 TiVCT |
|---|---|---|
| Required fuel | Minimum 87 octane | Minimum 87 octane or E85 |
| Firing order | 1-4-2-5-3-6 | 1-4-2-5-3-6 |
| Ignition system | Coil on plug | Coil on plug |
| Spark plug gap | .028-.031 (0.7 - 0.8 mm) | .049-.053 in. (1.25 - 1.35 mm) |
What happens if you don't gap a spark plug correctly?
When you don't have the proper spark plug gap, that can lead to premature wear, ignition system stress, and even cylinder misfires. The space between electrodes must be wide enough to create a sufficiently energized spark.
How often should you replace your spark plugs on a 5.3 L engine?
every 30,000 miles
How often to change spark plugs for your own vehicle may be different compared to another car owner in Crawfordville, but the most commonly recommended interval is every 30,000 miles.
What is the spark plug gap on a 5.3 L engine?
The new spark plug, P/N 12571164 with AC Delco P/N 41-985, is gapped to 1.01mm (0.040 inches) when the spark plug is made. The spark plug gap is set during manufacturing and should not be changed or damage to the spark plug may result. Any new spark plug found to not be properly gapped should not be used.
What is the spark plug gap on a Chevy?
0.035 inches
The Chevy 350 spark plug gap is 0.035 inches.
Use your feeler gauge or gap gauge to measure the current gap. It should fit perfectly at the measurement listed above. If you can't fit the 0.035-inch blade or coin through the electrodes, the gap is too small.
